Engine Coolant: Inspection

CAUTION:

Do not use water instead of coolant.
Refer to "Recommended Materials" service information for the recommended engine coolant. < Refer to COOLANT , RECOMMENDED MATERIALS, Recommended Materials. >

Park the vehicle on a level surface.
Make sure the engine coolant level in the reservoir tank is between "FULL" and "LOW" when the engine is cold.
NOTE:
If the engine coolant level drops, make sure that there are no engine coolant leakage, and add engine coolant to the "FULL" line.
